Why are you using ASP style tags? PHP doesn't compile on it so what
other advantage does that give you other than not being compatible
with most installs?
Get rid of your error hiding. Suppressing errors means you don't see
them either therefore cannot fix them. The better solution is to turn
display_errors off and leave logging on.
My guess is that it is trying to link to a directory, a . hidden file,
or something else that shouldn't be there. If it were my script I
would probably use a glob() type solution so that I can pick the ext's
I want.
